10,500. A small bush of opener places. Flowers vivid magenta- 
rose. Very abundant on rocks and cliffs, forming wide and 
often procumbent masses. Very profuse with scentless flowers 
of bright carmine-rose with crimson-purple tube. Farrer 1567, 
May 20, 1920. 
N.W. Yunnan. 
A species remarkable for the ash-grey coloration of the under 
leaf-surface brought about by the combination of black scales and 
the grey-white coating of wax-bearing papillae. Only seen else- 
where so far in Rh. spodopeplum, Balf. f. et Farrer. The flowers 
and their disposition recall the Brachyanthum phylum of the 
Campylogynum Series in some degree—in the umbels and in the 
calyx—but the stamens are very different and the gynaeceum has 
a long not deflexed style. True these features of the stamens and 
carpels appear in Rh. aureum, Franch. another of the Campy- 
logynum Series and this may be the affinity. In any case the 
form is an interesting one and quite new. Noteworthy is the 
ovary which is not truncate at top but tapers into the lepidote 
style as it does in Rh. aureum also. The deep grooving of the 
ovary is very prominent and the carpels readily separate one from 
the other
